AudioTool Pro Mod Apk 8.4.2 (Premium) for Android‏ Free Download


SPL (deciBel) Meter that includes RT60, Leq, Sone, Spectrum Analyzer, Spectrogram, Chart Recorder, Sign Generator, Polarity Checker, and Mic calibration.

Really useful by “Sound and Imaginative and prescient” journal. Beloved by Audio Engineers worldwide: try the Evaluations!

Features: 1/1, 1/three, 1/6 & 1/12 octave RTA modes, Leq (wideband, Octave, variable period), Sones (Loudness), RT60 (wideband, Octave), Peak Retailer, Spectrogram, Waterfall, Peak frequency, Impulse, Quick, Medium & Gradual filters, Flat & A/C Weighting and movie business X Curve, Averaging, SPL Chart Recorder, Noise Standards (NC and NR), White/Pink Noise, Sine, Sq., Triangle, Sweep, Log Sweep, Warble, Ramp and Impulse indicators & loudspeaker polarity checker, L/R choose. RTA Retailer & Load, Hann home windows, pinch to zoom, scroll to heart.

Examples of latest updates (April 2019):
v8.zero New Characteristic: Load one or two saved spectrum recordsdata and show each alongside the realtime knowledge.
v8.1 New Generator choice: swap part of Proper stereo sign
v8.2 New Menu choice “Set Decision” permitting to set 4096, 8192, or 16384 pattern lengths
v8.three New 1/12 Octave RTA mode

Unique ISO 1/three Octave Calibration – can appropriate on your cellphone’s microphone response. Octave calibration discs are moved up or right down to receive a flat response, and match the general SPL to that of an exterior meter. Save/Restore of Cal recordsdata (standard Dayton Audio iMM-6, MicW i436, additionally supported).

Use: gig measurements, house theater, acoustics, automotive, and many others.

AudioTool FFTs units of microphone samples. Aliasing lowered by Hann windowing. SPL calculated in realtime. Spectra could also be saved, then loaded and displayed with the dwell spectrum. The “Retailer” button shops the present dwell spectrum – “Load” exhibits a listing of saved spectra to pick out.

To cover the buttons, faucet the display. To revive them, faucet once more. To zoom the dimensions, pinch the display. To maneuver the dimensions, drag it up or down (left or proper).

A pair of cursors will be proven: every will be moved to any place, and can show the SPL & time/frequency values there. The cursors will be turned on and off within the Menu.

The loudspeaker polarity checker can be utilized to test whether or not a loudspeaker is wired in part: join the AudioTool output to the speaker beneath check, choose “Polarity” from the sign generator display, then return to the RTA display. If the speaker is out of part (polarity reversed) AudioTool will present “Pol —“, in any other case “Pol +++” if the speaker is in part.

The Noise Standards operate exhibits a set of NC contours overlaid on the 1/1 Octave RTA show and the calculated actual time present NC worth can be proven.

The Chart Recorder exhibits a transferring hint of the SPL measurements over the previous few minutes.

RT60 measurements (how a lot reverberation or echo there’s in a room or corridor) will be made utilizing the “RT60” operate, triggered utilizing a loud clap (or related) to or with Pink Noise from the AudioTool generator.

The Sign Generator generates White and Pink Noise, Sine, Sq., Triangle and Ramp waves, Sine Linear and Log Sweeps, Warbles and Impulses. The generator makes use of a number of cycled buffers, refreshed randomly so making certain actually random White and Pink noise.

The frequency accuracy of the Sign Generator is often round 1%. Sine wave constancy is nice all through many of the audio vary. Different indicators’ main and trailing edges will present ringing and lowering frequency response artifacts within the higher ranges, relying on the cellphone getting used.

The above description is a really terse version of the On-line Guide, which can be accessed right here:
